Yes. You need to remove it from use first. # swap -l swapfile dev swaplo blocks free /dev/zvol/dsk/rpool/swap 182,2 8 4194296 4194296 # zfs get volsize rpool/swap NAME PROPERTY VALUE SOURCE rpool/swap volsize 2G - # swap -d /dev/zvol/dsk/rpool/swap # swap -l No swap devices configured # zfs set volsize=1G rpool/swap # /sbin/swapadd # swap -l swapfile dev swaplo blocks free /dev/zvol/dsk/rpool/swap 182,2 8 2097144 2097144 Note: in the first "swap -l" above, blocks == free, so the swap device was not actually being used. If your swap device is in use, then you might not be able to delete it, so you'll have to make another, then shuffle the data around. -- richard > Thanks > Karl > > > > > > > > > > > > > > CONFIDENTIALITY NOTICE: This communication (including all attachments) is > confidential and is intended for the use of the named addressee(s) only and > may contain information that is private, confidential, privileged, and > exempt from disclosure under law.
